I've found it now. I had to find the original season in UHD and then I …I've found it now. I had to find the original season in UHD and then I was able to change the seasons.It's in UHD and HDR, makes their faces looks very red.

I watched the whole show in HD before I found the UHD version. I'm a bit peeved about that. No idea why Amazon have the UHD version so well hidden.

I thought the show was too much like the old Top Gear, very disappointing because I thought Season 1 was much better. A star in a car again. Pointless.

I wonder if the red faces colour problem is because although I have a 4K TV, it's doesn't have HDR.

Ours does and it was the same, yeah not sure what to think of the show it was good but still think it needs to up it’s game. Do wonder as well about the star in the car piece does seem pointless as you said.
